Distribution of bioluminescent fungi across old-growth and secondary tropical rain forest in Costa Rica

Most research on bioluminescent fungi is concentrated on their taxonomic relationships, while the basics of their natural history and ecological relationships are poorly understood. In this study, we compared the distribution of bioluminescent fungi between old-growth and secondary forest as related...

In this study, we compared the distribution of bioluminescent fungi between old-growth and secondary forest as related to four different soil types at the tropical rainforest of La Selva Biological Station in Costa Rica. The study was conducted during the wet season of 2009. Bioluminescent fungi were sought following eight different transects distributed evenly in old-growth and secondary forests across four different soil types, covering an area of 9 420m². We found fungi in four different substrates: litter, fallen branches, dead trunks, and roots, for a total of 61 samples. Correspondence analysis showed that the occurrence of fungi and soil types were related (inertia=0.21, p=0.071). We found a significant relationship between the presence of fungi and the distribution of soil types (X²=18.89, df=9, p=0.026). We found only three samples with fruiting bodies, two of which had Mycena and the other had one fungus of the order Xylariales (possibly Hypoxylon sp., Kretzschmariella sp., Xylaria sp.). Future work will concentrate on exploring other aspects of their ecology, such as their dispersal and substrate preference. This information will facilitate field identification and will foster more research on the distribution, seasonality, reproductive phenology and ecological requirements of this group of Fungi.<br>La mayoría de las investigaciones sobre los hongos bioluminiscentes se ha centrado en relaciones taxonómicas. Los aspectos básicos de la historia natural y relaciones ecológicas de este grupo son poco conocidos. En este estudio, comparamos la distribución de hongos bioluminiscentes entre el bosque primario y el secundario en la Estación Biológica La Selva, Costa Rica en relación con cuatro tipos de suelo. El estudio se realizó durante la estación lluviosa del 2009. Se buscaron hongos bioluminiscentes en ocho transectos distribuidos de manera uniforme en el bosque primario y secundario y en cuatro tipos de suelo, cubriendo un área de 9 420m². Se encontraron hongos en cuatro sustratos: arena, ramas caídas, troncos muertos, y raíces muertas, para un total de 61 muestras. Se encontró una relación significativa entre la presencia de hongos y la distribución de los tipos de suelo (x²=18.89, gl=9, p=0.026). Sólo se encontraron tres muestras con cuerpos fructíferos, dos de ellos del género Mycena, mientras que el otro presentaba un hongo del orden Xylariales (posiblemente Hypoxylon sp. Kretzschmariella sp. Xylaria sp.). Futuras líneas de investigación deben concentrarse en aspectos básicos de la ecología del grupo, tales como su dispersión y preferencia de sustrato. Esta información fomentará una mayor investigación sobre la distribución, la estacionalidad y fenología reproductiva, y los requerimientos ecológicos de este grupo de hongos.http://www.scielo.sa.cr/scielo.php?script=sci_arttext&pid=S0034-77442013000300004bioluminiscenciabosque tropical lluviosoCosta RicahongosLa SelvaMycenabioluminescence fungiCosta RicaLa SelvaMycenatropical rain forest
